Mounting the VLP in the Inverted Orientation
If the detector is fitted with a LCD Programmer and/or a Display Module, re-orient these to the
upright position. Mount the detector in inverted orientation onto the mounting bracket.

Mounting the VLP without a mounting bracket
In the event the detector has to be mounted directly onto the mounting surface, remove the
chassis from the mounting box. See
Replacing the chassis/Air Inlet Pipe Manifold on page 32 for
details.
Use the four keyhole slots to secure the mounting box to a flat surface, ensuring that it is
horizontally straight. Re-install the chassis into the mounting box. Carefully re-connect the looms
and complete the cabling prior to closing the front cover. See
Internal Wiring for VLP on page 34
Note: The laser detector chamber, head processor card and flow sensors are factory
calibrated as a matched set. Separating the set and replacing it with components
from another set may cause the detector to malfunction, requiring re-calibration at
the factory.
